What are the best pricing strategies for energy efficiency and demand response programs?
Energy efficiency and demand response are key strategies to reduce greenhouse gas emissions, improve grid reliability, and lower electricity bills. But how can utilities and customers adopt these strategies in a cost-effective and fair way? In this article, you will learn about some of the best pricing strategies for energy efficiency and demand response programs, and how they can benefit both the environment and your wallet.
One of the simplest and most common pricing strategies for energy efficiency and demand response is time-of-use pricing. This means that the electricity price varies depending on the time of day, reflecting the different levels of demand and supply on the grid. For example, the price may be higher during peak hours, when the demand is high and the grid is stressed, and lower during off-peak hours, when the demand is low and the grid has excess capacity. Time-of-use pricing encourages customers to shift their consumption to off-peak hours, reducing peak demand and the need for expensive and polluting peaker plants. It also rewards customers who generate their own electricity from renewable sources, such as solar panels, during peak hours, when they can sell it back to the grid at a higher price.

A utility provider may offer TOU pricing schemes in which the cost of power varies depending on the time of day. Peak hours, when energy demand is high (typically early evenings), may see higher costs than off-peak hours, when demand is lower (late at night or early morning). Customers participating in these TOU programs are urged to use power during off-peak hours to take advantage of cheaper prices. They may plan operations such as dishwashing, laundry, or charging electric vehicles during these periods to reduce grid load during peak hours.

The best pricing strategies for energy efficiency and demand response programs often involve Time-of-Use (TOU) pricing, which varies rates based on demand at different times, and Peak Time Rebates, offering incentives for reducing usage during high-demand periods. Additionally, implementing Critical Peak Pricing (CPP) during peak demand times can effectively encourage energy conservation.
Another pricing strategy for energy efficiency and demand response is dynamic pricing, which is more flexible and responsive than time-of-use pricing. Dynamic pricing means that the electricity price changes in real time, depending on the current conditions of the grid, such as the availability of renewable generation, the occurrence of outages, or the weather. For example, the price may spike during a heat wave, when the demand for air conditioning is high and the solar generation is low, or drop during a windy day, when the wind turbines are producing a lot of electricity. Dynamic pricing signals customers to adjust their consumption according to the grid needs, reducing congestion and volatility. It also enables customers to participate in demand response programs, where they can receive incentives for reducing or shifting their load during critical events.

Smart thermostats, such as those supplied by Nest or Ecobee, use dynamic pricing principles to optimize energy use. They can modify heating and cooling settings in response to real-time energy pricing or demand indications from utility companies. During peak demand hours, for example, or when energy costs rise owing to high demand or restricted supply, the smart thermostat may automatically modify the temperature settings to decrease energy use.
A third pricing strategy for energy efficiency and demand response is inclining block rates, which is more progressive and equitable than flat rates. Inclining block rates means that the electricity price increases as the customer's consumption increases, creating a tiered structure. For example, the first 100 kWh of electricity may cost 10 cents per kWh, the next 100 kWh may cost 15 cents per kWh, and so on. Inclining block rates discourage excessive and wasteful consumption, promoting energy conservation and efficiency. It also protects low-income and vulnerable customers, who tend to consume less electricity and pay lower bills, while charging more to high-income and large customers, who tend to consume more electricity and pay higher bills.

Ce système est équitable car il permet aux moins favorisés d'avoir une électricité peu chère pour les besoins vitaux et ceux qui consomment beaucoup (jacuzzi) peuvent probablement se permettre de payer cher. En France, nous avions proposé de mettre en place un tel système mais cela a été rejeté par le conseil constitutionnel. Car selon cet organisme, il faut une égalité de traitement entre les particuliers et les entreprises. Si le taux de bloc incliné est facile à imaginer pour des particuliers, c'est plus difficile à mettre en place pour les entreprises. Car si l'entreprise énergivore augmente trop son activité, ses couts de productions vont alors augmenter et elle va partir à l'étranger, où l'électricité est moins chère.
A fourth pricing strategy for energy efficiency and demand response is net metering, which is more supportive and attractive for distributed generation. Net metering means that customers who have their own renewable energy systems, such as solar panels or wind turbines, can offset their electricity consumption with their electricity production, and only pay for the net difference. For example, if a customer consumes 500 kWh of electricity from the grid and produces 400 kWh of electricity from their solar panels in a month, they only pay for 100 kWh of net consumption. Net metering incentivizes customers to invest in renewable energy systems, reducing their dependence on fossil fuels and their carbon footprint. It also benefits the grid, by providing clean and distributed energy resources that can enhance reliability and resilience.

Assume a homeowner decides to install solar panels on their roof. Solar panels may generate more power than the home consumes on bright days. With net metering, any extra electricity produced is sent back into the system, and the homeowner receives credit for it. while the solar panels create more energy than the home requires (for example, during daytime hours while the residents are gone), the extra energy is sent back into the grid. This extra energy is used to offset the homeowner's future energy use, effectively "running the meter backward." As a result of the surplus energy delivered to the grid, the homeowner earns credits on their power bill.

Attention à ne pas confondre "net metering" (comptage net) et "net billing" (facturation nette) "net metering" = c'est comme si le compteur "tourne à l'envers" si un site en autoconsommation solaire produit davantage qu'il ne consomme. Tous les kwh, aussi bien ceux injectés que sous tirés, ont le même prix. "net billing" = l'electricité est vendue et achetée au réseau à un prix différent à chaque heure de la journée. Ainsi si je vend 10 KWh à 1€/kWh pendant les heures pleines et que j'achète 10 KWh à 0,3€/kWh, je vais gagner 10€-3€=7€ alors que j'ai injecté autant que j'ai produit.
A fifth pricing strategy for energy efficiency and demand response is performance-based incentives, which is more rewarding and motivating for customers who achieve specific outcomes. Performance-based incentives means that customers who participate in energy efficiency and demand response programs can receive payments or credits based on their actual performance, such as the amount of energy saved, the peak demand reduced, or the emissions avoided. For example, a customer who installs an energy-efficient appliance may receive a rebate based on the estimated energy savings over its lifetime, or a customer who participates in a demand response event may receive a payment based on the actual load reduction during that event. Performance-based incentives recognize and reward customers for their contributions to the grid and the environment, creating a positive feedback loop and enhancing customer satisfaction and loyalty.

When implementing pricing strategies, consider factors such as consumer preferences, affordability, regulatory requirements, technological advancements, and potential impacts on vulnerable populations. Additionally, assess the feasibility and effectiveness of each pricing strategy in achieving energy efficiency and demand response goals in specific market contexts.

It's also important to consider the importance of transparency, education, and customer engagement. Providing clear and accessible information about pricing structures, benefits, and potential savings empowers customers to make informed decisions about their energy usage. Offering educational resources and support services can help customers understand how they can optimize their consumption patterns to maximize savings while supporting grid reliability and sustainability goals. Finally, engaging with customers through communication channels such as newsletters or online platforms fosters a sense of partnership and encourages active participation in energy-saving initiatives, ultimately contributing to the success of pricing strategies.
